Is there a way to not use "float"? If you have to use it, you need to handle RTL
as well.

[Tim Song, 2013/10/15 22:23:31]

Done. I never considered the RTL case, thanks!

Other than using a table, I can't really think of another way to align the
checkbox label with the dropdown subsetting.

I put a CL https://codereview.chromium.org/26238007/ that attempts to do this
without using float. The idea is to put the checkbox label and select subrow in
a the same div to make them align.

[Tim Song, 2013/10/16 19:41:46]

Ah, I wasn't too familiar with -webkit-box, -webkit-box-orient, and
-webkit-box-align. I changed the layout to do as you suggested and removed the
floats.
